` Application led February 21, 1922. Serial No. 538,297.

Thedevice forming the subject matter of this applica-tion is a cultivator, and the invention aims t-o provide novel means for ad justing the soil-engaging elements with respect to each other and with respect to the surface of the soi'l.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the invention, parts bei-ng broken away; Figure 2 is a top plan ofthe implement; Figure 3 is VYa rear elevation wherein remote parts are omitted; Figure 4 is a top plan showing the main and auxiliary beams, together with vthe means whereby the beams are supported and adjusted with respect to each other; Figure 5 is a crossV section on the line 5-5 of Figure 4.

The implement forming the subject matter of this application includes a trame, comprising a bar 1 whereon ground wheels 8 are supported. rlhe implement includes a hanger, denoted by the numeral 11. hanger 11 comprises a depending intermediate loop 12 and depending side arms 14. Sleeves 17 are mounted on the ends of the arms 14 of the hanger 11. A `sleeve 2O is mounted on the lowermost portion of the loop 12 of the hanger 11.

A clamp 31 is mounted on the sleeve 2()v which is carried by the loop 12 of the hanger 11. A socket 32 is pivoted at 33 to the clamp 31 for horizontal swinging movement. The socket 32 carries a rearwardly extended main beam 34. Lateral stubshafts 35 are mounted on the socket 32. Sleeves 37 are carried by the stub shafts 35 and are adapted to rock thereon. Clamps 38 are connected to the sleeves 37. Sockets 39 are'pivoted at 42 to the clamps 38 for horizontal swinging movement. Auxiliary beams 4 3 are located on opposite sides of the main beam 34 and are secured in the sockets 39. A transverse guide 44 is attached intermediate its ends, as at 45, to the main beam 34. The auxiliary beams 43 are mounted to slide laterally in the guide 44.

Because the sleeve 2O is mounted to rock on the loop 12 of the hanger 11, and because the sleeves 37 are mounted to rock on the stub shafts 35, the beams 34 and 43 can be swung vertically. The auxiliary beams 43 can swing laterally, since the sockets 39 are The main beam 34 can participate in the lateral movement of the auxiliary beams 43, because the The 'socket 32 which carries the beam 34 is piv- 'oted at 33 to the clamp 31` Clamps 46 are attached to the sleeves 17. Sockets 47 are pivoted at 48 to the clamps 46 for lateral swinging movement.- The sockets 47 carry rearwardly extended supplemental beams 49 disposedr outwardly or the auxiliary beams 43. Becausethe sleeves 17 can rock on the lower ends of the side arms 14 of the hanger 11, the supplemental beams 49 may have' a vertical swinging movement. Since the sockets 47 which carry the supplemental beams 49 arepivoted at 48. to 'the clamps 46, the beams 49 may have a lateral movement. i

Soil engagingy members 59 are mounted on the beams 49, 43 and 34.

The lower ends of arms 56 are connected pivotally with the auxiliary beams 43. The lower ends of the arms 57 are connected pivotally with the supplemental beams 49. The arms 56 and 57 are crossed on each other and are connected pivotally at their point of crossing as shown at 58. A segment 59 is mounted on the upper end of the arm 56. A lever 60 is ulcrumed at 61, at its forward end, on the forward arm of the segment 59 and, consequently, on the upper end of the arm 56. A link 62 forms a pivotal connection between the intermediate portion of the lever 60 and the upper end of the arm 57. The lever 6() carries a latch mechanism 63 adapted tol cooperate with the segment 59. l/Vhen the latch mechanism 63 is disengaged from the segment 59, the lower ends of the arms 57 may be swung toward and away from the lower'ends of the arms 56. In this way, the supplemental beams 49 may be adjusted laterally toward and away from the auxiliary beams 43, the soil-engaging members of the said beams being adjusted accordingly. When the latch mechanism 63 is engaged again with the segment 59, the beams 39 and 43 will be held in any position in which they may have been adjusted, laterally, with respect to each other.

A primary lever 64 is carried by a fulcrum bolt 65 mounted in a segment 66 supported on the beam 1. A latch 69 on the lever 64 cooperates with the segment 66. A iexible, and if desired resilient connection 70 extends between the lower end of the .primary lever 64 and the main beam 34.

The main beam 34 supports ak segment 78. A lever 79 isfulcrumed at 81 on the segment 78 and is provided with a latch mechanism bar 34. The forward end of a connecting rod 83 is pivoted to the slide, the rear end of the connecting rod being pivoted to the lever 79. The inner ends ot links 84 are pivoted to the slide 82, the outer ends ot' the links being pivoted to the auxiliary beams 43. Y A

Through the instrumentality of the lever 79, the connecting rod 33, the slide 82 and the links 84, the auxiliary beams 43 may be swung on their pivotal mountings 42, laterally, toward and away from the main beam 34, thereby to regulate the width of the area which is swept by the soil-engaging members on the beams 34 and 43.

Through the instrumentality of the arms 56 and 57, the beams 49 may be adjusted with respect to the beams 43 in a horizontal direction. rl`he lever 79 and attendant parts constitute means for swinging the beams 43, laterally, toward and away from the beam 34. rlhe lever 64 and coacting parts constitute means :tor raising and lowering the supplemental beams 49 simultaneously with the main beam 34 and the auxiliary beams 43.

Having thus described the invention, what is claimed is In a cultivator, a frame including a hanger, a main beam mounted on the hanger for vertical and lateral movement, auxiliary beams disposed on opposite sides of the main beam and supported on the main beam for vertical and lateral movement, a guide carried by the main beam and receiving the auxiliary beams slidably for lateral movement, the guide restraining the auxiliary beams against vertical-swinging movement independently of the main beam; means for swinging the auxiliary beams laterally with respect to the main beam, said means comprising a slide mounted for reciprocation on the main beam, links pivoted to the auxiliary beams and to the` slide, a lever fulcrumed on the main beam, means for holding` the lever in adjusted positions, and a link connecting the lever with the slide; supplemental beams disposed outwardly of the auxiliary beams and mounted on the hanger for vertical and lateral movement, adjustable connections uniting the supplemental and auxiliaryv beams to vary the angle therebetween, means connected t0 the main beam for raising and lowering all of the beams, and soil-engaging* elements` on the beams. y

In testimony that I claim the foregoing .as my own, I have hereto affixed by signature.

FRANK DIVIN.
